TIME-STAMP.

To all whom it may concern.

Be it known that I, CLARANCE C. SnsLEY, a citizen of the United States,residing at Perth Amboy, Middlesex county, New Jersey, have inventedcertain new and useful Improvements in Time-Stamps, of which thefollowing is a specication.

My invention has reference to stamps or devices for impressing the timeof receipt etc., on paper and the like, such as the hour and minute, andthe invention has for its object to provide simple and effective meansfor causing the hour and minute indicators to be regulated and operatedby means of electric current controlled by a timepiece or clock.

My invention comprises the novel details of improvement and arrangementsof parts that will be more fully hereinafter set forth and then pointedout in the claims.

Reference is to be had to the accompanying drawings forming part hereof,wherein,

Figure 1 is a perspective view of a time stamp embodying my invention.Fig. Q. is a plan view, enlarged, of the dial and t-ime pointers. Fig. 3is a side elevation of the operating devices of the stamp removed fromthe casing of Fig. 1. Fig. i is a central sectional view, enlarged, ofthe operating devices of the stamp. Fig. 5 is a cross sectionsubstantially on line 5, 5, Fig. 4, looking in the direction of thearrows, and Fig. 6 is a detail view of the magnet and controlling wheelsof the stamp.

Similar numerals of reference indicate corresponding parts in theseveral views.

In the drawings the numeral 1 indicates a suitable casing shown providedwith a detachable cover 1a upon which is mounted a stamping pad 2 showncarried by a plunger 3, that is guided by a bracket 5, supported uponcover 1a and raised by a spring a, but it will be understood that anysuitable means for controlling the stamping pad may be provided.

At 6 is a dial member carrying the numerals l to 12 to indicate thehours, which dial has a centrally disposed opening or socket (3 in whichare located the hour pointer or arrow 7 and the minute pointer 8. Thecasting for the dial number 6 is shown received in an opening 2a incover 1a and held to the cover by screws 9.v The minute pointer 8 isshown carried upon a flange Specification oi' Letters Patent.

Patented Mar. 8, 1910. serial No. 295,225.

10 extending upwardly from a disk 10a fitted to rotate within the socket(ia of dial number 6, the disk 10a having a hollow shaft or stem 10bpassing downwardly through a bearing or opening in the bottom of dialmember 6, and by preference I interpose anti-friction balls 11 betweenthe bottom of dial member 6 and disk 10a to permit free revolution ofsaid disk. Within the recess 10C that is formed by the flanges 10 ofdisk 10a is located the disk or support 7a of the hour pointer 7, saiddisk having a shaft 7 passing through the bore in shaft or stem 10b soas to rotate therein, and b preference I rovide anti-friction balls 12between the disks 7 a and 10a to permit free rotation of one withrespect to the other. The arrangement of the parts is such that theupper or working surface of the numerals of the dial and of the pointers7, 8 are substantially iiush so that when an inking ribbon 13 lies overthe dial and pointers and a paper is placed upon the ribbon under pad 2and the latter is stamped down upon the paper the impression from thedial numerals and the pointers will be printed upon the paper, and thethrust of the pad is transmitted from the pointers through the balls 11,12 to the bottom wall of the dial member G.

The means I have shown for rotating the hour pointer 7 one revolutionduring 12 hours, and for rotating the minute pointer 8 one revolutionduring each hour are as follows :To the shaft 10 of the minute pointerdisk 10L are secured ratchet-wheels lil, 15 having an equal number ofteeth, as sixty teeth each, facing in opposite direc tions, asillustrated in Fig. 5. Said ratchets may be formed on a single piece ofmetal or in separate pieces secured together. A dog 16 carried by an arm17 engages ratchet 14, a spring 1S carried by arm 17 holding dog 16against the ratchet, arm 17 being secured to a shaft 19 that isjournaled in a frame 20 shown secured to and depending from the lowerpart of dial member 6. 21 indicates a spring-acting back-stop dog showncarried by frame 2O and acting with rachet 14E to prevent reversemovement of the latter. In order to prevent ratchet 14: from overrunningthe proper distance that it is moved by dog 16 at each minute stroke, Iprovide a dog or iinger 22 carried by arm 17 and adapted to engage theteeth of ratchet 15, the relation ot said doe' Q2 to the teeth ot'ratchet 15 being such that as arm 17 causes dog 16 to move ratchet 'ietthe distance ot a tooth the dog 22 will encounter a tooth ot ratchet 15and thus prevent the ratchet 14; from being pushed too tar beyond theproper distance tor each step or movement of the pointer S for theminutes to be indicated. Thus, as arm 17 is rocked the minute indicator8 will be moved one st-ep equal to aminute on the dial for each toi-wardmovement oit dog 1G. The means I have shown tor oscillating arm 1 7 onestep for each minute ot time comprises a magnet 2 3, whose armature 24kis secured to shaft 19, a spring connected at one end with said shaftand at the other end with frame 20, as by a screw 26, acting against theaction of the magnet in well known manner. The terminals 26, 27 of themagnet are shown connected with binding posts 2S, 29 on trame E20, fromwhich line Wires 30, 31 lead, as through a hole inbox 1,to amake-and-break device of any suitable kind controlled by a timepiece(not shown) in well known manner. As shown in F 1, the wires 30, 31connect with contact-springs 32, a iinger 34tcarried by an arbor 35rotated by the timepiece causing said contact springs to make and breakthe circuit, a suitable battery (not shown), being provided tor thecircuit. In the arrangements shown it is designed that linger 34 berotated once for each minute to make and break the circuit each minuteof time.

In order to cause the hour pointer 7 to rotate once during twelve hoursof time, or 1/12 as tast as the minute pointer 8, I provide thefollowing arrangement 1-To the shaft 7b ot the hour disk 7 is secured agear 37 that meshes with a gear 3S which is secured to or made integralwith a gear 39, gears 3S and 39 being mounted to rotate on a shaft orscrew 40 that is shown carried by ratchet 15, and gear 39-meshes with agear it1 that is held from rotation, as by being` secured to trame 20,whereby as ratchets 14 and 15 are rotated the gears 38 and 39 will becarried bodily around gears 37 and 41. The ratio ot this gearing is suchthat it'or each revolution ot ratchets 14 and 15 around the axis otshaft 7b, the hour pointer 7 will be driven 'forwardly 1/12 of arevolution while the minute pointer S makes one complete revolution. Theratio of gears 37, 3S, 39 and i t1 to produce theabove named results'may be as tollowst-gear 37 to have twenty-tour teeth, gear 38 to havetwenty-two teeth, gear 39 to have twenty-four teeth and gear t1 to have22 teeth; and thus as gears 3S and 39 are carried bodily around gear 39and roll on the stationary gear 41, they will cause gear 37 to rotate,and by reason of the ratio ot .said gearing 37 will be advanced only1/12 of a revolution tor each complete revolution oit gears 38, 39bodily around gear stl. In accordance with the arrangements describedthe gearing etc., may hang suspended from cover 1fL within casing 1 whenthe cover is secured thereon, and as finger 3a closes the circuit of themagnet once each minute the armature 34- will oseillate shaft 19 andcause dog 1C to operate the ratchets and thereby move thc minute pointer8 one step forward each minute, and the gearing 37, 3S, 39 and a1 willcause the hour pointer 7 to move torward 1/12 as 'tast as the minutepointer S, and thus when an impression is made upon the paper the minuteand the traction ot the hour will be indicated by the respectivepointers.

I have shown a single time stamp electrically connected with amake-and-break device to be controlled by a timepiece, but it will beunderstood that while a single timepiece may be used to control a singletime stamp, a plurality ot time stamps can be connected with a single ormaster clock by arranging the circuit in any well known manner, so thatall the time stamps so connected with the timepiece will have theirrespective minute and hour pointers adj usted synchronously as theminutes pass.

My invention is not limited to the particular deta-ils ot constructionshown and described as they may be varied withoutdeparting from thespirit thereof.

Having now described my invention what I claim is 1. A time stampcomprising a dial member having a socket, a minute indicator diskjournaled therein, a plate having an opening receiving said member, anarm carried by said plate and extending over said member, a pad carriedby said arm over said member, antifriction balls between the dial memberand said disk, the minute indicator disk having a recess, an hourindicator disk within said recess, anti-friction balls between theminute and hour indicator disks, a wheel connected with the minuteindicator vdisk and suspended below said dial. member, means to impartstep-bystep movement to said wheel, a gear connected with the hourindicator disk below said wheel, a` stationary gear below the Firstnamed gear, a pair of united and pivotally carried by said wheel andmeshing with the `in .licator gear and with the stationary gear.
